Any advice for stuttering?

Any advice for stuttering? When I was 12 years I got scared by a dog and ever since then I began to stutter. I am 22 years old now and I feel like the stutter has gotten worse. It’s hard for me to say certain words and I always have speech blocks like I can’t let out a sentence. This has ruined my social life. I don’t want to talk to anyone but I’m embarrassed of my speech. Does anyone have any advice to help my stutter get better? Thank you in advance.
